Subject: "Polar Bear" Scoop build
Date Posted: 19 June 2010 at 11:00pm

As some of you may remember, late last year I designed and built two scoops of my own. My friends decided the model is called Polar Bear due to it being perhaps the northernmost scoop design ever. Yesterday we started building two more. Today's task was to take it slow and put one together without glue, just to see how everything aligns out. Tomorrow we're going to take it apart, add the missing stuff (dog leg...) and hopefully get both ready for painting. There are going to be two connector panels, another with 2x NL4 and another with 2x NL8. We have two V18-1000s waiting to be loaded. For these two we decided to cut all side panels ("roof" and "floor" included) 18mm too deep to get a small lip to the back to improve the grip when grabbing underneath the bin while taking it up some steep stairs or in any other situation where there may be need for more than two pairs of hands carrying it. The lip doesn't make it any deeper because there are still casters beneath, making the actual full depth quite a bit more than what the box in itself is.     BTW the Makita impact screwdriver is a lovely tool to work with! Highly recommended. |

| Nnope, actually quite small, mostly because of the "extended" dogleg / triangle which moves the throat really near to the front of the chamber. We forgot to put in in there while dry-building this. |

  First bins with mouth bracing. Also first bins that we built without having to rush them to a gig next day, so I guess one thing leads to another (not building so quickly leads to better build quality etc.) We really should add bracing to other boxes too, though. btw these pictures were taken between 9 and 10 pm this evening  |

Updates: As I'm still located in Shanghai, sound system co-owner sent me pictures of our Polar Bears, now almost finished. Finally we have something that could be considered as "whole", though 1850s are wrong cabs for midbass job. Older scoops are going to have mouth bracing as well and all old cabs are going to have a coat or two of Warnex. We are also going to have some proper square grilles for the drivers. Big thanks go to my friends and co-owners making all this sillynes possible. Next move will be something completely different, first step may be getting rid of the 1850s (can I see two more scoops coming up...?) and building USBs to go in the middle, if I don't feel like finishing my 8643 hybrid's 2x12" version. The mighty V18-1000:  Mouth bracing, FINALLY  The stack, missing two midtops in here:  |

Well, I really cannot comment on how they sound compared to other scoops as I haven't heard any other than what was in last Notting Hill Carnival (A.S.S was in different league compared to others, missed Aba Shanti I though). I think they really need a bit of EQing around 40-60hz area, that is if I really really want that same "flavour" and warmth as Kayak had with his ASS float. Of course these sound well heavy without EQ too. They are definitely on a par with 1850 horn what it comes to sensitivity. We are driving both with same amplifiers and both are loaded with V18, so easy comparison. We use these for 30-70hz and 1850 from 70 to 120, we may push them to 130 or 140hz at some point just for fun. What do you consider as large / medium / small chamber in scoops, Lev? These ones have around 60 liter chamber |
Posted By: levyte357
Date Posted: 13 July 2010 at 3:04pm
IMHO, would class small chamber as <55L, 55-65L as Medium Chamber, and >65L as large chamber. ------------- "Who am I? I'm the guy who does his job.. You must be the other guy". |

ASS S118 has around 53L - small chamber. around 60 is medium, around 70 is large. To calculate chamber volume, I need inner width (600mm?), distance for inner baffle and throat oppening.------------- Support the scoop technology, larger mouth plays louder! |

Driver with larger Vas than V18-1000, would really make use of that larger chamber. However, would also need min BL=25/Xmax=12, Think you should try one of these in there... http://forum.speakerplans.com/2x-18-turbomax-1000-drivers-fane-chassis_topic41060.html - http://forum.speakerplans.com/2x-18-turbomax-1000-drivers-fane-chassis_topic41060.html ------------- "Who am I?

18N860; realy slow dynamik speaker. EPB 62, Qts 0,37 Mms 277g, this is not good horn driver, great for BR.. ------------- Support the scoop technology, larger mouth plays louder! |
Posted By: pfly
Date Posted: 13 July 2010 at 6:11pm
Just check out what 18N850 does in Hogs  Tony Wilkes tested two with Smithers' Hogs I believe. ...On the other hand you are kind of right, but then again scoop isn't the most typical horn. My guess is that 18N860 has large enough VAS and just enough of BL to work in there, it sims a bit poorer than V18-1000 though. It would be really interesting to compare 18N850, 18N860 and V18-1000 in my scoop |

Sims only tell you half the story, and are often very optimistic. From 1st hand experience, can tell you Turbomax 1000/Fane 18-1000 sounds better than PD 1850/V18-1000 in all the medium chamber scoops I have heard. They are basically more musical/flatter response. With true Xmax evidenced, by smooth sound, even at high power with plenty of Eq. The very expensive B&C Neo was a joke compared to the above. If new/used Neos provided same price performance ratio as Turbomax 1000/Fane 18-1000, would definetly be more interested iin them. EDIT:Compared to the weight of PD1850, the Turbomax is a Neo. ------------- "Who am I? I'm the guy who does his job.. You must be the other guy". |

| But by your definitions this is a large chamber scoop and pfly is talking about a BMS neo driver, not a B&C. |
Posted By: pfly
Date Posted: 13 July 2010 at 7:10pm
| I'm not about Nd in this but I honestly believe that BMS 18N860 is one of the very very very top sub drivers today, regardless of magnet material. Like all drivers, it won't suit every loading technique, but general quality and performance should be top notch. |
Posted By: levyte357
Date Posted: 13 July 2010 at 8:03pm
Typically, drivers suited to scoops fall into 2x categories, those perfect for small chambers and the rest. So you are more likely to hear about small or medium chamber scoop drivers. Mentioned B&C, as that is also a Neo that on paper/Sims seemed to excel, however actual performance in scoop was very dissappointing. Point being, time has shown, simming Neo drivers in scoops, is "often" pointless, proof being in actual listening, as opposed to simming ferrite drivers, you will often get mostly accurate approximation, of real world results. ------------- "Who am I?

to be honest i'd ignore Hornresponse altogether. it is unable to really tell how it is going to sound. the best example being: sim a Turbomax 1800 in a medium/small scoop and the sims say it would be awesome, but we all know these drivers need more than a big chamber, so it seems, otherwise they sound like a bag of spanners. i can only think of 2 common drivers that truly work in tiny chambers with 10+mm xmax, thats the PD1850 and the V18-1000. btw those scoops look cool - did you leave the lip around the rear of the box to provide a handle all the way round for when it's on castors?

I personally would not use the 860's in anything but a large BR when you need its ability to go very low, Cinema Subs etc. However in large chamber Scoops the 850v2 works very well. No idea how it compares to the Tmax etc etc never compared them, only with the Void 1200,s. Maybe do a comparison one day. Tony |

another measurement bump, this time outside, with 2nd and 3rd harmonics. For many reasons this is much more accurate than earlier |

The response measurements posted above are impressive as very few scoops will go below 40Hz. 30Hz is quite an achievement. Was the scoop placed in a corner when the measurement was made? Lee |

All measurements done with a stack of four. Indoor measurement was done near back wall. Low-ish ceiling. I'm more impressed with the distortion figures. I think these things sound phenomenal. They are definitely sub box with little "kick" available, but in 30-80hz range they sound fast, precise, warm and smooth. Not as "clinical" as Lab, but still there is plenty of detail that for example Meyer 700HP wouldn't reveal. Also I can give them everything that Infinite 5 bridged per pair can give and they don't show any sign of stress what so ever. |

@pfly Thanks for doing the polar bear scoop! We are a collective of dub enthusiasts from Graz, Austria, and are very interested in it. We have talked with Dub Smugglers Soundsystem, they also have build Your design. Buildphase-photos are available at their Facebook account: https://www.facebook.com/media/set/?set=a.10150996514247223.482590.128547807222&=3 Among the many photos which you can also find there:        So Dub Smugglers (& propably others -tell us!) already have fun  , we are in the planning phase right now. As this is our first build, we eagerly try to look at every detail and try to speak with as many people as possible to get it right. As your original image uploads of the plan are offline, we would kindly ask If you (or, please, anybody else who would have them) could fix that, as well as we would be very curious if there were some improvements made to the design since the last 5 years. We plan to use a 5axis CNC machine to cut the scoop(s), so we would like to work as thoroughly as possible. If you would find some flaws in our plans, please tell us. I think that I can also speak for Dub Smugglers when we say thank you for designing such a wonderful scoop. |

Well, I never said so. You've to read it again... We met Dub Smugglers in Vienna, at a dance of botheration HIFI, where we also played. This is where the contact comes from, and they brought our attention to this design. And then I browsed their fb page and I found lots pictures of Polar Bears ;-) Still, I am curious to get to talk with pfly, as he's the one behind the design; This, the fact that the original plans are offline, and that we want to share & get more infos, is the motivation of my post. By no means would I have posted just these Photos if I would have I found more:   more photos & detailed info is more than welcome . |

All credit due to Mr Pfly Polar bear + PD1852 + K20 = amazing Was only running on 3 scoops most of the night at the warrior clash, I managed to blow a PD1850 fairly early on - was a non genuine recone. Strange how the other 3 genuine coned ones continued to work.......but that's a whole other topic

I've tried the inf8 with the PD1852 a few times, and whilst having a great tonality, the drivers can take more than it can give Inf8 not having enough power! madness :) There's quite a few big sounds that have heard the difference and have made the move I was pushing 6k peaks if not more at the weekend into 4 scoops, and it was only pulling 10a at most The efficiency is incredible We ran 6 x SBH a SIDE off the K20 the other weekend, which was equally ridiculous |

Great stuff. Witnessed same on the big old crest 9001 clipping away on 52/51no more power to give and like you say drivers got way more to give.yeah void running out of power is mad tho few say iration having same problem as well with new drivers.only reason not changing drivers really as can not run to a k20 ha ha so will stick with the void for now. Regularly haveit to 16 -19 amps tho feel 1850 pretty much at limits there. Yeah amazing efficiency on the power soft from what you describe. ------------- TRENDSETTER SOUND SYSTEM |

Also, what drivers suit well for this particular design? everyone is talking about the 1852 of course, but I'm looking at a less expensive solution, like 18LW1400. Standard parameters for scoop suitable drivers are ok or should I look for something in particular? THX

That is looking proper. I'm glad you guys are enjoying this box. Only thing this box needs is some 2-6dB cut around 80Hz, depending on taste. As this peak is close to where most users would LPF these anyway, alternatively users can leave a small gap into the crossover or just cross these electronically lower to filter the excess energy out. |

I find it strange and equally interesting that people struggle to power their drivers with inf8? Too many occasions we've had the power to destroy 51/52 Tmax1500 and more. EDIT: 52 sounds warmer than 50. Handles more power better on the lows. Id expect a better sound, more pressure nicer lows. Instead i haven't heard that yet with polar 52. Sam i prefer the 1850 scoop you built compared to what ive heard from polar. Also quite alot more boxes infront of the polar from what ive heard. But too many variables ie how they been set up whos operating etc. I can only comment on what ive heard from them and not what i have got out of them as i havnt played them yet. ------------- Sound Hire/Sales new/used equipment. |

Imagine how much it saddens the designer, when he hears about his freely provided plans, being used to build cabs, which are then sold on an industrial scale, with no commission earned by him.  ------------- Global Depopulation - Alive and Killing. |

It seems strange to me, the hundreds of requests for this plan over the years, where as, a perfectly acceptable, free 18" Scoop plan, alternative to the Superscooper 18", is also freely available, on this site, that people are building. ------------- Global Depopulation - Alive and Killing. |

It's because Sinai used them on his mark 1 rig and built quite a reputation with them so loads of people want to have them. Also the allure of not being able to get the design just adds to the drive to get the plans, much like an unreleased piece of music that everyone chases down. They are great scoops for sure, my wife has 8 of them and they definitely get the job done. ------------- Melbournes Rootical Warrior Roots - Dub - Steppers http://www.facebook.com/adrians.wall" rel="nofollow - facebook page |

The precise plan I was talking about. personally suggest the Superscooper 18 for Void V18-1000s, The Mykey "Scaled up Fane", for everything else. The "Knowledgeable", will modify Mykey plan, to suit their driver of choice...  ------------- Global Depopulation - Alive and Killing. |

thank you i plan to build only 2 or 3 scoop stack, and maybe should be better with mykey scoop than superscooper ? thank again

| I'm planning on building four scoops too for dub and dubstep and its clear that polar bears are not an option. I already have 4 pd1850/2 but will probably upgrade later. Would mogale or mykey be better? |

I will save you the time based on the responses over the last few months. The MyKey design is the superior updated design proven and available. |

| In what way does it compare to mogales? Because for me it's very important that in a group of 4, it can reach around 30hz and has good SPL. The Mykeys look easier to build too as I don't have to do the curved sections. |

Neither scoop will hit around 30 with authority especially with just four , a stack of six hogs struggles with that with a bit of a longer horn path. And with authority I mean with the same impact and feeling as 40+ hz. If you don't want to build and maybe buy new scoops check out the stakx scoop it has a bit of wizardry in the chamber and a bit longer horn . . |

I've known Frederik for many many years now and we both respect each other and our skills from what I can tell. From knowing the internal structure of the scoop he's got, there's nothing super complicated going on. What's happening is shuffling things around to basically circumvent that otherwise fixed width-wise dimension. With the split entry to the horn, you don't really change the behaviour -- not at these frequencies. You could move them all to one side and they'd behave the same as a horn. But not in the chamber as horn throats! If you'd merge them you'd get a different response *because* of the fact the speaker is in a chamber that has its own feelings and thoughts err physics too. So this split throat, extra extension of that tube, and so forth allows: - Allow the total cross sectional area of the throat/entrance to be smaller - ^While not restricting the outflow to the horn of the lowest frequencies (the aspect ratio of the tubes is responsible for that) - Circumvents the part where in older designs, the chamber and throat are otherwise very indistinct, so making the throat larger would actually steal part of your chamber too. The size of the opening you need for large bass waves to pass through in say a superscooper would make the cross sectional area so huge that it also poses lower resistance to the driver. - Hence this allows the higher compression ratio and driver control of a smaller throat entry, without the compromise on your low end you'd get from a very wide, but narrow in height slot of a superscooper.
Does this help with the "special magic"? It's not complicated or advanced new acoustics. It's just a case of cleverly rearranging the cross sections and such, and observing that doing as such (and as done in the SH118) slightly decouples the chamber size and behaviour and the compression ratio and the side effects of narrowing the opening of your throat (which is your only way of reducing the cross sectional area total with a fixed width!) If that still doesn't make more sense, then.. I can't help, but I can give other examples of speakers that have done this. Say, the Jensen Imperial with its internal left and right exits out of the chamber that then merge into a large horn. (I lost track of my train of thought forgive me) |

I would argue, no 18" Scoop is going to hit 30hz with authority, even in a stack of 6x. Anyone who says a Scoop must play 30hz, and not mention with which driver, does not know what they are talking about. Even if loaded with a wonder 18" driver, in building with immaculate mains supply, and if the crew are using the best amps money can buy. And let's face it, most crews are not using €600 drivers, or Powersoft X4L amps, or playing in venues with 3ph power. if a Scoop system can play down to 38hz with authority, with 4x Scoop stacks, nothing will sound like it is missing, and most people will think it is playing lower. ------------- Global Depopulation - Alive and Killing. |

Firstly, I would suggest selling the 1850/2 now, and getting 1851s. Only driver I liked better than PD 1851s, are 18NLW9601. I would suggest the Mykey plan, 738mm depth version. with following mods,

Unfortunately the cab has to be built first as we have just spent our budget on the wood however we would probably end upgrading drivers two months after the cabs have been build as 4 PD1850/2 can probably sell for £250 each maybe but getting 4 PD1851s would cost £400 each :/
Thanks. |

Would expect you can find used 1851s for up to £275 each.
Make total cab width 636mm Wide Yes, just remove inner 18mm panel off driver baffle, basically slightly increasing chamber
Cross brace is very old fashioned. Single 36mm brace is one way, more modern approach, would be 2x 18mm horizontal braces, full grill adds to the look, especially if you add grill foam.
